Abstract

The utility model relates to a large high-neck flange forging and rolling die. The die comprises a die body, a through hole is formed in the center of the die body, the die body is sleeved on a driving roller of a rolling machine through the through hole, the side wall of each of the top and the bottom of the die body is provided with a groove, and the bottom of the die body is provided with a lower flange. The die is simple and reasonable in structure, the die body and the lower flange are matched with the rolling machine, the wall thickness of a flange forging is uniform, machining allowance is reduced, and the production cost is reduced; and the die has the advantages of high utilization rate of materials, energy conservation, low labor intensity and high quality of a forged flange.

Description

Large-scale hubbed flange is forged and is rolled over mould
Technical field
The utility model relates to the flange forging apparatus, specifically, relates to a kind of hubbed flange forging mold.
Background technology
Hubbed flange is a kind of large-sized annular spare, is widely used in the industry such as oil, chemical industry, metallurgy.At present, adopt open die forging compressing tablet, punching, saddle support reaming and rolling rolling to expand the square-section blank for the hubbed flange moulding, final again by be machined into required flat board, inside and outside the shape of high throat area.Adopt above-mentioned process to forge hubbed flange, particularly as far as the iron tower flange of inside and outside hub, its cross section is made up of dish portion and neck; Because diameter, cross section are bigger, so the means through machining (like pin, mill) transform the blank square-section cross section of hub shape as, required machine-finish allowance is big; Cause the energy consumption of material consumption and forging big; Cost is high, labour intensity is big, and the annular element wall unevenness is even, and the hubbed flange of forging is of poor quality.
The utility model content
The utility model forges the problems referred to above that exist in the process to existing hubbed flange, has proposed a kind of simple in structure, easy to use, high efficiency and the measured large-scale hubbed flange of flange matter and has forged and roll over mould.
The technical scheme of the utility model is: a kind of large-scale hubbed flange is forged and is rolled over mould; This mould comprises die body, and the center of die body is provided with through hole, and die body is sleeved on the Ring Rolling Machine driven roller through through hole; On the top of die body and the sidewall of bottom groove is set all, the bottom of die body is provided with down rib.
Preferably, following rib is installed on the Ring Rolling Machine driven roller.
The beneficial effect of the utility model is: the utility model is simple and reasonable; Die body is used with following rib and Ring Rolling Machine; The wall thickness of flange forging is even; Reduced machine-finish allowance, reduced production cost, the stock utilization height is saved energy consumption and labour intensity is low, the flange quality of forging is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model specific embodiment.
Accompanying drawing 2 is the user mode figure of the utility model specific embodiment.
The specific embodiment
For structure, characteristic and other purpose that can further understand the utility model, combine accompanying drawing and appended embodiment to specify as follows at present, illustrated embodiment only is used to explain the technical scheme of the utility model, and non-limiting the utility model.
A kind of large-scale hubbed flange is forged and is rolled over mould; This mould comprises die body 1, and the center of die body 1 is provided with through hole, and die body 1 is sleeved on the Ring Rolling Machine driven roller 2 through through hole; On the top of die body 1 and the sidewall of bottom groove is set all, the bottom of die body 1 is provided with down rib 3.Following rib 3 is installed on the Ring Rolling Machine driven roller 2.
When making flange, die body 1, die body bottom groove, following rib 3 and core roller of ring rolling machine 4 form " L " type shaping road of a sealing, and flange blank material 5 passes L type shaping road and relatively rotates and the hole enlargement moulding through Ring Rolling Machine driven roller 2, core roller of ring rolling machine 4.
